Abstract

3-Methacryloxypropylpolysilsesquioxane (MAPS) was prepared by acid- or base-catalyzed hydrolytic polycondensation of 3-methacryloxypropyltrimethoxysilane (MAS). MA-PS coating film was prepared by dip-coating on organic, metal and inorganic substrates, including poly(ethylene terephthalate), aluminum, stainless steel, and glass. The coating films on poly(ethylene terephthalate) and glass showed high adhesive strength. The hardness of coating films increased with increasing heat treatment temperature, whereas they decreased with increasing H2O/MAS molar ratio. The refractive index of coating films increased with increasing heat treatment temperature. In addition, flatand transparent free-standing films (0.24-0.27 min thickness) were prepared from MA-PS that were crack-free after heat treatment at 1000 degreesC.
